The Strike Industries Enhanced Castle Nut and Extended End Plate Combo is a refined upgrade over standard parts kit components, offering both functional advantages and improved aesthetics. The steel castle nut is lengthened to better support the receiver extension’s threads and visually align with the extended end plate. The end plate features a rearward-positioned Quick Detach (QD) sling mount, preventing sling interference and accidental hand pinching during weapon manipulation in tight spaces or under stress. Installation is straightforward, with a simplified takedown pin and detent setup using a set screw. Note that this setup may eliminate the fully collapsed position on some stocks to accommodate the QD socket.
